OAKLAND, Calif. 
Stephen Curry had 25 points, 10 assists and seven rebounds on a sprained right ankle, and the Golden State Warriors held off the Los Angeles Lakers 109-103 on Monday night.

David Lee added 23 points and 12 rebounds, and Klay Thompson scored 22 points to propel the Warriors to a 25-point lead early in the third quarter in a matchup with huge playoff implications. Golden State (41-31) improved to a game ahead of idle Houston (39-31) and 4 1/2 games in front of the Lakers (36-35) for sixth place in the Western Conference.

Los Angeles' lead over Utah (35-36) for the final playoff spot is down to one game. The Jazz beat Philadelphia 107-91 in Salt Lake City earlier Monday night.

Kobe Bryant scored 36 points and Steve Nash had 21 points, nine rebounds and seven assists in an otherwise lackluster Lakers effort. Los Angeles has lost three straight games, and the latest was never even close.

Questionable to play since spraining his twice surgically repaired ankle in Saturday's victory over Washington, Curry sat out the morning shootaround and often grimaced during a pregame workout at the arena. Warriors coach Mark Jackson called Curry a "game-time decision," though Lakers coach Mike D'Antoni never doubted Curry would play - or play well.

With the dynamic point guard leading the way, the Warriors received contributions from all over.

Thompson hit three of his six 3-pointers in the first quarter, and Curry made another one. Festus Ezeli added an alley-oop from Jarrett Jack and put back a miss to give Golden State a 28-14 lead.

The reserves kept the momentum going, with Jack outrunning everybody for a coast-to-coast layup and tossing in a floater to start the second quarter. He had 19 points.

Harrison Barnes also converted a layup and a difficult jumper while getting fouled by Antawn Jamison, and Curry's second 3-pointer put the Warriors up 44-24.

The usual sprinkling of Lakers fans shouted chants of "M-V-P!" when Bryant shot free throws. But they were drowned out by the Warriors fans who sold out Oracle Arena for the 25th straight game and screamed "Beat L.A.!" at every chance.

The frustration for the Lakers finally started to show. First, Metta World Peace jawed at Lee, then awkwardly patted the All-Star forward's head once officials intervened. A few minutes later, Dwight Howard picked up a technical foul while exchanging words with Lee and an official after he was called for a foul on Lee's layup.

Both Lakers big men struggled on both ends. Howard had 11 points and 15 rebounds, and Pau Gasol was held to seven points and eight rebounds as he works his way back from a right foot injury.

The half ended when Lee dunked the ball with 1.9 seconds left, World Peace threw away an inbounds pass and Curry lobbed to Andrew Bogut for an alley-oop. Bryant just walked through the tunnel behind the basket and into the locker room as his team inbounded the ball, taking one quick glance at the scoreboard: Warriors 63, Lakers 40.
